Abstract: A method for producing asphalt using a high percentage of RAP (recycled asphalt pavement) in the total aggregate raw material. A counterflow rotary drum dryer is used to dry the raw material. The extent of the burner flame in the dryer is limited such that the RAP does not come into direct contact with the flame. The hot gases leaving the dryer pass to a wet scrubber.

Abstract: A portable paving material mixing apparatus includes a material hopper, a rotatable mixing drum, and a discharge bed, all configured to be supported on a vehicle trailer. A burner heats material within the mixing drum. Embodiments of the mixing apparatus include a rejuvenator application system suitable for hot mix asphalt, cold mix asphalt, hot in-place recycling, and asphalt based concrete mixing. The apparatus rapidly processes a batch of material sufficient to fill 5-7 potholes, has sufficient carrying capacity to process multiple mixer batches, and stores prepared material in the discharge bed while the next batch is being prepared in the mixing drum. The apparatus enables a more efficient, less equipment-intensive paving repair process without the need for a separate millings loader or hot box.

Abstract: A method of making hot mix asphalt using recycled asphalt in which tertiary air is mixed with products of combustion at an exit of a refractory-lined chamber to produce hot controlled temperature process air, the temperature of the tertiary air being increased while the temperature of the products of combustion is decreased to adjust a temperature of the hot controlled temperature process air. Particles of the recycled asphalt are heated by exposing the particles to the hot controlled temperature process air in the rotary counter-flow dryer and mixer and moisture is removed from the recycled asphalt with the hot controlled temperature process air.

Abstract: The invention relates to a method and a plant for producing asphalt mixture and is directed in particular to the recycling of recovered asphalt. In order to achieve recycling of up to 100% recovered asphalt and to produce an asphalt mixture with the required quality, it is provided according to the invention that at least the drying and heating of the asphalt granulate and/or aggregates are carried out in a low oxygen atmosphere. The low oxygen atmosphere is achieved by supplying low oxygen gases with an oxygen content of maximum 10%, preferably with an oxygen content of maximum 5%. The conveyance of the heated and dried asphalt granulate and/or aggregates, the siloing and mixing with bitumen to form a new, incorporation-ready asphalt mixture also usefully take place in a low oxygen atmosphere.

Abstract: A method is disclosed for recycling asphalt roofing shingles and incorporating them into hot mix asphalt for use in applications such as asphalt pavement construction. Unlike previous methods, the asphalt from ground shingles is mixed with and becomes an integral component of the asphalt binder, instead of acting primarily as part of the aggregate. The asphalt content of the shingles mixes with heated asphalt binder to produce a single asphalt phase, and the asphalt from the shingles acts as asphalt in the final composite.
